XCode 4.2 clang seg fault

Question

剛剛升級到Lion和xcode 4.2。現在，當我重新編譯我的節目，我收到這些錯誤：

1. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1806:35: current parser token ';'
2. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1762:1: parsing Objective-C method 'updateWithTouchLocationMoved:withEvent:view:'
3. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1762:1: in compound statement ('{}')
4. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1771:2: in compound statement ('{}')
5. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1789:3: in compound statement ('{}')
6. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1796:4: in compound statement ('{}')
7. /Users/XXX/Code/iPhone/XXX/Code/Scenes/GameScene.mm:1799:5: in compound statement ('{}')
clang: error: unable to execute command: Segmentation fault: 11
clang: error: clang frontend command failed due to signal 2 (use -v to see invocation)

沒有什麼奇怪圍繞這些行號怎麼回事。沒有複合語句，如果(a == b)類型的東西只是簡單的。某些錯誤行號甚至不在語句中，只是空行或{大括號。我懷疑行號不準確。我現在有點死在水裏。代碼在4.1下編譯好。

有什麼建議嗎？

Answer 1

我停止了編譯器崩潰。註釋掉的代碼行線後，看到這實際上發生後我到達這條線：

shape.shapeType |= kTypeBreakable; 

做...

shape.shapeType = shape.shapeType | kTypeBreakable; 

...編譯罰款。所以呢......

shape.shapeType |= 0x00000200; 

kTypeBreakable是設置爲0x00000200

shapeType枚舉只是一個對象 - 對象變量有一個getter /設置。

非常非常奇怪的編譯器錯誤。
